Aaron's New Stepsister

Desc: Erotica Sex Story: Aaron gets a new stepsister, and things get very complicated. Things aren't all what they seem.

Aaron Sanders was shocked when he heard that his father had remarried. His mother had died when he was young, and it had always just been him and his dad. When he was going to college at Pitt, his father told him during his senior year that he was dating a woman, but getting married only three months into their relationship was a huge shock. Heather was a woman who had been divorced a long time and he guessed they just fell into a mindset of hurrying up because they were both in their forties. Aaron just hoped that his dad had set up a great prenuptial agreement because he felt like this was rushed into and might not last very long – his father was one of the most successful attorneys in the Phoenix area, and he feared that this woman was a gold-digger who wanted his money. His father was the one who always told Aaron not to make rash decisions growing up, and now he's seemingly made one himself.

What's more, Heather was the mother of two kids that Aaron had gone to high school with and knew somewhat. Stephen was in his grade and he recognized him and had a few classes with him, but they were never friends or had hung out before. Kristy was two grades below them; Aaron only had a few conversations with her. She was on the cheerleading squad so he saw her during his football games, and his girlfriend at the time was the cheer captain and always said that she was a really nice and fun girl. Aaron remembered thinking that Kristy was extremely hot, he never acted on it or anything because he was always faithful to his girlfriend at the time, but it was still weird to think that this girl that he was previously attracted to was now his step-sister.

His father, Keith Sanders, had married in March (no ceremony, just a court house wedding and that's it – he told Aaron not to bother to fly back home to Phoenix for it so it wouldn't interrupt his studies during his last few months of school) and now it was June. Aaron was 23, had just graduated Pitt and was looking for a job. He had been the Panthers starting quarterback the two previous years and had garnered some NFL draft buzz, but this last year he suffered a season-ending injury three games into the season and had to sit out. He had always counted on making it to the NFL in some capacity (even as just a backup QB, at least) but his injury had made that impossible, and now he was forced to look for other job options. Because he wanted to focus on football, his major at Pitt was "Communications" – the easiest one possible, but now he would have to rely on it to get real non-football work and was in a bad situation.

Thus, Aaron was forced to fly back to Phoenix to live at the house he grew up at. He thought he was just going to live with his dad, but the marriage had changed that equation, and now it would be a packed house. Stephen had also recently graduated and was coming back from San Diego State, while Kristy was a currently a student at local Arizona State and commuted from home to save money.

Aaron was kind of pissed at the situation. He was sure that one of the kids had taken his room; they had a guest room as well but no other bedroom suitable so he wasn't sure how the living situation would shake out. He supposed the workout room would have to be converted into a bedroom. He sure hoped one of those other two would be the ones to live in the guest bedroom and the other room – he wanted to stay in the bedroom he had grown up in, not only was he more comfortable with it, but it was much larger as well.

Sitting on the plane headed to Phoenix, Aaron ruminated about the possibilities, but at the same time he was somewhat excited to have siblings for the first time. He had grown up as an only child, so he never really had the experience of bonding with siblings at all – maybe it could be fun. It could be a lot of fun to have a brother to hang around and throw the football around and play video games with.

He had no idea how to interact with Kristy – what do sisters and brothers do together, exactly? The fact that he was previously attracted to her and probably will continue to be made things complicated as well. Well, at the very least, it would be nice to have something to look at around the house, even if he could never act on it. He decided that there was really no shame in being attracted to her – it's not like they were a blood relation, they didn't grow up together, and they even sort of knew each other beforehand. Aaron was less excited about having a mother figure for the first time – he certainly hoped Heather never tried to boss him around.

After the plane landed at Sky Harbor, Aaron got off the plane and saw his new family together for the first time.

"Hey son," his father said as he came up and hugged him. "Welcome home!"

Heather came up to him next. Although he went to school with her kids, Aaron had never met her before, and when he saw her he immediately knew why his father wasted no time in locking her up. Heather was in her 40's but could have easily passed for early 30's, with long black hair, a slim waist and relatively large breasts for her figure. She clearly had a little bit of plastic surgery done at some point but it had paid off, and she looked a lot like actress Courteney Cox.

"Hello Aaron! So nice to finally meet you. I've heard so much about you from your father, he showed me your football games and everything. I guess you're my new stepson now!"

"Yeah, I guess so. Nice to meet you too," Aaron chuckled nervously. This was a pleasant surprise - even if she acts like a total bitch and tries to control me, now I have two women to look at around the house, he thought.

Stephen came up to him next and they shook hands. "Hey man, nice to see you again after all these years."

Aaron greeted him back and shook his hand but couldn't help but feel a little awkward – they knew each other to some degree in high school and certainly had no animosity but they were never friends or talked to each other outside of class. Aaron was the star football player while Stephen was a rocker who had his own band – positions that gave both of them plenty of popularity and got them laid plenty, but not really circles that crossed often. Stephen was 23 now, the same age as Aaron.

Next up was Kristy. Aaron had to stop his jaw from dropping when he saw her. He thought that she was smoking hot in high school, but she had upped a level in the time since then and turning 21. She had long black hair, an absolutely adorable face with just the right amount of freckles, and a killer body that included a nice round ass and a slim waist and a toned stomach. Her breasts were small but perky in high school, but they had definitely grown in the last four years, in what appeared to be a natural fashion.

Aaron went in for a handshake. Kristy threw his hand away and went in for a hug. "Oh put that away, you're my new big brother, that deserves a hug!" she said as she squeezed him and made a squealing noise. Aaron bucked his lower body away as he correctly assumed that his dick would get hard from having her tits pressed against his chest.

"Hey there – nice to see you too, new stepsister!" Aaron laughed. Aaron began to reevaluate his situation. He was excited at the possibility of seeing an attractive girl around his house initially, but he knew that he would never act on it because he would never put his father in that awkward position. But he didn't expect it to be like this – the best case scenario was a major case of blue balls, and the worst case scenario was he might get caught staring at her and creating an awkward situation for everyone.

"Damnit, why couldn't I just have met with her separately and not have our parents be married? I could have fucked the shit out of her without ramifications," Aaron thought to himself.

The five of them chatted as they grabbed Aaron's bags and drove home. As they were getting into the car, his father's five-seat sedan required the three new siblings to be in the back squished together. Kristy chose to be seated in the middle between Aaron and Stephen. Aaron had to pull his shirt over his pants as he could hardly contain his erection at the fact that Kristy's shapely ass was rubbing up against him in her tight jeans.

As they drove home, the new family chit-chatted. Aaron found out that Heather was a relatively successful pharmacist, which somewhat alleviated his concerns that she was a gold digger out for his dad's money. He also found that although they've only recently started dating that they've actually known each other for over 20 years – they first met when Aaron and Stephen were attending the same pre-kindergarten classes.

Eventually he and Stephen got to talking. "Hey man, I got to say, I have followed your football career pretty closely," Stephen stated, "and I was definitely rooting for you because it was cool to say to my friends that I knew that successful Pitt quarterback from high school. Although, I will admit, I was a little upset when you beat my SDSU Aztecs in the 2010 season opener," he laughed. Aaron appreciated this but was a little sad as it reminded him of the potential he had before the injury ruined his career and potential future.

Finally, they arrived home. The five of them hung out for a few hours and talked and shared a bottle of wine. Aaron didn't dare ask about sleeping arrangements – he was pretty sure that it would cause some sort of conflict. When it came time to go to bed, his father approached him when they were alone.
